I like early 4-speed HydraMatics. But- repairing them can be very expensive, and few transmission shops will service them.
'57 is a Dual-Coupling, which eliminates the harsh shifting of earlier Dual-Range HydraMatics. But it suffers from a performance standpoint; the 1-2 and 3-4 shifts can not be made quickly, since time is required to fill the front coupling with fluid.
